NCOA Export File Not Generating

We've opened a ticket about this, but wouldn't hurt to ask here so we can possibly move forward sooner. We've got 2 issues when trying to run the NCOA Export Utility. We are self hosted. v15.1

1) When we try to export the full list (1.3 million records) the export errors out. 

2) We tried a smaller list, that did complete, but no file was generated in the path even when the path was local (c:\test.txt)

Has anyone ran into these issues? Any tips on how to solve?

Any help is greatly appreciated!
